Looking for new ways to get some perspective on how our bodies process food, some UK scientists have built an artificial stomach that simulates digestion. The machine is made from plastics and metals, all strong enough to withstand the acids that are part of digestion, and is controlled by computers, able to mimic all the physical and chemical reactions associated with eating. It is even capable of vomiting.

The designer, Dr Martin Wickham, is hopeful that "his model will help scientists understand more about how food gets processed in the gut, and which nutrients get absorbed." This knowledge could lead to new definitions of superfoods, which are supposedly the healthiest of foods, determining which nutrients are absorbed the fastest and how to get the most from what we eat. There are commercial applications, as well, and companies have already shown an interest in borrowing the machine to test out some of their new food products (health-type products) release a specified nutrient to the stomach that the company claims it does.

A group of Swedish university students is taking part in a study that is recreating Morgan Spurlock's fast food experiment, Super Size Me, in laboratory conditions. Under the supervision of professor Fredrik Nyström, two groups of young medical school students are stuffing themselves with fast foods and avoiding exercise. All of the calories they eat must come from fast food, although they are allowed to make breakfast at home so long as it was "bacon-and-eggs based".

Nyström thought it would have been more difficult to find people willing to participate, but the students were more than eager. More men than women applied and the chosen were the most highly motivated, who were likely to stick to the 6,000 calories-a-day diet. All their food throughout the study would be paid for and they were provided with bus passes so they would not have to walk any more than necessary. The only control on the study was that the Swedish ethics board said the participants must be removed from the study if they increased their bodyweight by more than 15%.

The kitchen at El Bulli, recently chosen again as the best restaurant in the world, is at the forefront of culinary innovation. Diners wonder how the food is done and chefs take sabbaticals just for the chance to visit. Without dropping everything and going to Spain, you can take a tour of the kitchen, too, via the Decoding Ferran Adria DVD. The DVD is hosted by Anthony Bourdain, who visits the "lab" in Barcelona and tracks the progress of food at the restaurant from a mere idea to a plated dinner, a process which can take up to 6 months.

A few short clips of the film are available, to get a taste of what you'll find on the full-length, hour-long DVD.

Scientists around the world are working to develop a reliable process that will grow meat in a lab from a few cells. So far, they have successfully grown meat tissue that, while it smells like meat, neither looks nor tastes very much like the real thing. The process has only been done on a small scale and the results resemble jelly. Flesh colored jelly. To get an idea of what this product currently looks like, take a look at PBS's virtual taste test, which compares the properties of lab meat to animal meat.

Scientists hope to see this jelly develop into something that looks and tastes like the cuts of meat that can be achieved from butchering a cow - without having to kill the cow and with the added benefit of being able to grow the meat at home in an incubator. Achieving this goal would nearly eliminate the need for animals in meat production and reduce the total energy and expense required to feed, raise, slaughter and transport those animals.

Meat from a non-sentient source presents an interesting problem for vegetarians, as many become vegetarians for ethical reasons alone, objecting to the practice of raising animals for slaughter. Because the initial culture cells can be taken without harming the donor animal, no animals would be harmed in this type of meat production. In-home meat growth might also limit access to truly natural meat, which may raise concerns of those who are against artificial and otherwise modified food products.

There is a short video segment available on the PBS website about cultured meat and a poll which reveals that 45% of respondents would eat the artificially grown meat. I can't honestly count myself among them.

The Wrigley gum company is on a mission to prove that gum is not something to be chewed for fun and to annoy teachers. After years of the underappreciation of the value of its products, the company has turned to science for some answers. The Wrigley Science Institute was founded to discover whether gum can actually aid in weight management, stress relief, or in boosting concentration, all claims that have been made and passed along by gum chewers over the years. If the Science Institute can find sufficient evidence, the company can then claim the health benefits of the product on the products' packaging or in ads.

Just think back to all the elemantary school teachers who told you not to chew gum in class. If the Wrigley Science Institute is right about some of their theories, those same teachers could be passing out sticks of gum before tests!
